Abstract

A programming system allows a user to program therapy parameter values for therapy delivered by a medical device by specifying a desired therapeutic outcome. In an example, the programming system presents a model of a brain network associated with a patient condition to the user. The model may be a graphical representation of a network of anatomical structures of the brain associated with the patient condition and may indicate the functional relationship between the anatomical structures. Using the model, the user may define a desired therapeutic outcome associated with the condition, and adjust excitatory and/or inhibitory effects of the stimulation on the anatomical structures. The system may determine therapy parameter values for therapy delivered to the patient based on the user input.

Claims

1. A system comprising:

a processor and a user interface,

the processor configured to;

receive an input specifying a selection of an implant location of one or more leads, and

place one or more lead icons on a model of a network of one or more interconnected anatomical structures of a brain of a patient based on the selection of the implant location of the one or more leads, wherein the model of the network includes at least one link indicating a functional relationship between at least a first anatomical structure and a second anatomical structure;

the user interface configured to display a graphical representation of the model of the network including the at least one link indicating the functional relationship between a first anatomical structure and a second anatomical structure, and a graphical representation of the one or more lead icons.

2. The system of claim 1, wherein the graphical representation of the one or more lead icons comprises an image of the one or more leads and one or more respective electrodes.

3. The system of claim 1, wherein the graphical representation of the model of the network comprises a model of a brain therapy associated with Parkinson'"'"'s tremor.

4. The system of claim 1, further comprising a memory device, wherein the processor is configured to retrieve the input specifying the selection of an implant location of the one or more leads from the memory device.

5. The system of claim 1, wherein the processor is configured to receive the input specifying the selection of the implant location of one or more leads from the user interface and based on one or more user inputs received at the user interface.

6. The system of claim 1, wherein the input specifying the selection of the implant location comprises one or more structures in the brain of the patient in which the one or more leads are located.

7. The system of claim 1, wherein the input specifying the selection of the implant location comprises one or more structures in the brain of the patient covered by an electrical field resulting from a stimulation therapy via the one or more leads.

8. The system of claim 1, wherein the input specifying the selection of the implant location comprises associations between one or more lead elements of the one or more leads and one or more anatomical structure boundaries within the brain of the patient.

9. The system of claim 1, wherein the processor is further configured to receive, prior to implantation of the one or more leads in the brain of the patient, an input indicating an intended implant location of the one or more leads and place the one or more graphical lead icons on the model of the network based on the intended implant location of the one or more leads.

10. The system of claim 1, wherein the processor is further configured to determine a relationship between an effect on a behavior of one or more structures in a brain network of the patient and changes in one or more therapy parameter values based at least in part on the implant location of the one or more leads relative to one or more anatomical structures of the brain of the patient.

11. The system of claim 1, wherein the processor is further configured to:

determine one or more therapy parameter values based on the model and the selected implant location of the one or more leads; and

control an implanted medical device to deliver a therapy to the patient via the one or more leads according to the determined one or more therapy parameter values.

12. The system of claim 1, wherein the processor is configured to receive an input indicating the model of the network of the interconnected anatomical structures of the brain of the patient, and determine the model of the network of the interconnected anatomical structures of the brain of the patient based on the received input.

13. The system of claim 1, wherein the processor is configured to define the model of the network of the interconnected anatomical structures of the brain of the patient.

14. The system of claim 1, further comprising an implantable medical device configured to deliver a therapy to the patient via the one or more leads.

15. A method comprising:

receiving, at a processor, an input specifying selection of an implant location of one or more leads; and

displaying, on a user interface, a graphical representation of a model of a network of interconnected anatomical structures of a brain of a patient, wherein the model of the network includes at least one link indicating a functional relationship between at least a first anatomical structure and a second anatomical structure, wherein the graphical representation of the model includes graphical links indicating the functional relationship between at least the first anatomical structure and the second anatomical structure, and wherein the graphical representation of the model includes one or more graphical lead icons placed on the model based on the selection of the implant location of the one or more leads.

16. The method of claim 15, wherein the input specifying the selection of the implant location comprises an indication of one or more structures in the brain of the patient in which the one or more leads are located.

17. The method of claim 16, further comprising:

receiving, by the processor, an input indicating the model of the network of the interconnected anatomical structures of the brain of the patient; and

determining, using the processor, the model of the network of the interconnected anatomical structures of the brain of the patient based on the received input.

18. The method of claim 16, further comprising defining, using the processor, the model of the network of the interconnected anatomical structures of the brain of the patient.

19. The method of claim 15, wherein the input specifying the selection of the implant location comprises one or more structures in the brain of the patient that are covered by an electrical field resulting from a stimulation therapy via the one or more leads.

20. The method of claim 15, wherein the input specifying the selection of the implant location comprises a location indicated by coordinates of a tip or an individual electrode of the one or more leads.

21. The method of claim 15, wherein the input specifying the selection of the implant location comprises associations between one or more lead elements of the one or more leads and one or more anatomical structure boundaries within the brain of the patient.

22. The method of claim 15, wherein displaying the one or more graphical lead icons comprises displaying images of the one or more leads and one or more respective electrodes of the one or more leads.

23. The method of claim 15, wherein displaying the one or more graphical lead icons comprises the one or more graphical lead icons placed on the model based on an intended implant location of the one or more leads which have not been implanted in the patient.

24. The method of claim 15, further comprising:
